I need to fill up 2 walls in my living room with pictures. Just ordered Ilford Multigrade fiber based matte paper but have some Ilford MG FB glossy paper left over that I want to use for "practice" exposures. If I get the exposure I am happy with using the glossy, can I use the same time/contrast settinigs on the matte to get the same results?
no those two papers can't be exposed using the same time. Both are different so you should make a test stripes to obtain a proper time for an exposure.
